  • the forces exerted on the top of the tower by the rotor-turbine assembly determine the load, i.e. the bending moments at all essentially horizontal flange connections and welds.
  • the ultimate strength is determined by the yield strength of the bolts and by the buckling strength of the tubular metal wall.
  • the welds are critical. During service, it is very difficult to inspect the quality of a weld. Also, on-site repairs are awkward.
  • Hybrid towers such as towers with concrete walls, poured between an inner and outer steel shell have also been proposed.
  • the problem is to assure the quality of the wall, once it has been poured.
  • tension means are required to keep the concrete wall under compressive forces.
  • concrete towers are not an economical solution.

  • the stiffness of the construction is increased by the presence of the flanges of the prefabricated metal wall parts, which act as a rib.
  • the transport of complete tower sections is no longer required, thus solving the transport problem.
  • the prefabricated metal wall parts are easy to transport with ordinary transport means such as trucks.
  • the size of the tower at the foundation is no longer limited by the transport restrictions and a wider base can be used. It also allows construction of higher towers because the size of the base is no longer an issue. The wider base results in a lower local pressure on the foundation, thus enabling to use a simpler foundation.
  • the tower is substantially composed of prefabricated metal wall parts.
  • the tower according to this embodiment relies on prefabricated metal wall parts as the load bearing elements, and are readily distinguishable from concrete towers, where a wall part serves as a mould for the concrete to be poured in and where, after setting, the concrete serves as the main load bearing material. It should be noted that the tower according to the invention does not comprise concrete as a load bearing material at the location of the prefabricated metal wall parts.
  • a tower according to the invention on top of a concrete foundation or base wherein the concrete base extends upwardly, the base forming the lower part of the tower, and a tower according to the invention forming the upper part of the tower.
  • first flanges and the second flanges of the prefabricated metal wall parts extend towards the interior side of the tower This enables to produce a tower where the rib, formed by the adjacent flanges, is located on the inside of the tower, leaving a smooth exterior appearance.
  • a smooth exterior leads to a reduced impact of wind force on the tower and a smooth exterior is considered to be visually more attractive.
  • the prefabricated metal wall parts having a height and a width, at least two of the prefabricated metal wall parts have a height which is about 2.5 times larger than the width of the bottom edge, preferably more than five times larger, more preferably more than 10 times larger.
  • the height of the prefabricated metal wall parts is to be understood to be the distance between the bottom edge and the top edge of the prefabricated metal wall parts when present in the tower.
  • the length direction is defined in the direction of the height of the tower.
  • the tower comprises prefabricated metal wall parts which are considerably higher than wide, thus resulting in long side edges of the essentially quadrangular portion of the prefabricated metal wall parts and thereby enabling long flanges being provided at least partly on the side edge thereof. These long flanges enable a large stiffening potential of the tower.
  • the first flange of a prefabricated metal wall part is attached to the second flange of an adjacent second prefabricated metal wall part by fastening means.
  • the flanges are now fixedly connected, thereby increasing the stiffening potential because of the double thickness of the rib.
  • Fastening means comprise for instance a weld or a rivet.
  • the fastening means comprise nuts and bolts. This enables to fasten quickly the first and second flange of two adjacent panels to each other.
  • the holes required for the bolts to be inserted into may already be present in the prefabricated metal wall parts or may be drilled at the site where the connection between the adjacent panels is made.

  • trapezial prefabricated metal wall parts are called for.
  • Conical towers enable to construct a tower with a large base and become slimmer with increasing height of the tower. Tapering can be over the entire height of the tower or over part of the length of the tower. The latter can also be achieved by using prefabricated metal wall parts to form essentially cylindrical tower sections and by using prefabricated metal wall parts to form essentially conical tower sections and combine these tower sections into one tower.
  • Kinked prefabricated metal wall parts may be used in the upper levels of a conically tapered tower or tower section for a wind turbine wherein the lower levels are made using prefabricated metal wall parts with an essentially flat quadrangular portion, thus reducing the number of prefabricated metal wall parts required for a full ring.
  • One prefabricated metal wall part with one kink in the essentially quadrangular portion in a given upper level ring will link up with two prefabricated metal wall parts which have an essentially flat quadrangular portion in the ring immediately below the upper level ring.
  • the kinked prefabricated metal wall parts contains more kinks, it may link up with a corresponding number of prefabricated metal wall parts with an essentially flat quadrangular portion.
